Negative pressure in grow tent

Really good info!
My new tent is holding 32 C & 32% RH, fans in & out, filter, Canna-soil, Canna-Vega under 600W in a 4 x 4 tent. 3 Lemon Haze photo sativas at 9 inches tall and healthy. They drink a lot, nice green and growing about 1" per day at 18/6.
The intention is to top and SCROG very soon. Just a little concerned about the temp/RH but it is constant. The night time condition seems to go to 20C and about 60% RH
@Hellraiser @beardless it doesn’t sound that different from your conditions - as a first timer - your knowledge has been really helpful.
